TinyGPU by TinyCorp is now available for Mac users to run external NVIDIA GPUs (RTX 30/40/50 series) over USB4/Thunderbolt for AI workloads. The setup requires an ADT-UT3G dock, SIP disabled, and the tinygpu driver. Confirmed by Tom's Hardware and TechRadar, AMD RDNA 2/3/4 GPUs also reportedly work. The 70-upvote r/LocalLLaMA post signals genuine builder interest in breaking the Mac+NVIDIA barrier for local inference, though the drivers are AI-specific (no gaming/display).
